, Application flled December 28, 1926, Serial no. 157,497: Renewed Harch21, 1928.

The object of thisinvention is to so construct the parts of a hydrant that the combined inlet-and-waste, valve may be withdrawn upwardly from the valve-chamber without unscrewing any part'below the surface of the ground or the stand-pipe from the valve-chamber, whereby the valve-washers may be readily renewed from time to time wlthout di ging up any "of the buried parts of the hy rant,as more fully hereinafter set forth.

Inthe drawing+ t 'F'g. 1 is a vertical sectional view;and

Figsi2, 3 and tarehorizontal sections on the respective lines indicated in Fig. 1.'

Referring to the drawing annexed by reference-characters, 5 designates the V usual stand-pipe, 6 the valve chamber' screwed to the lower end thereof and having an inlet 7 at its bottom and an outlet 8 leading outwardly near its upper end, this outlet being for the purpose of draining the water re .maining in the stand-pipe after the.inletvalve is closed. This waste or drainoutlet valve-seat 9 arranged out of verticalalinement with the central inlet 7. The main inlet-valve 10 is attached to the lowerend: of a pipe-like rod 11, and the main valve 10 is provided with anofiset waste-valve 12 at its upper end which carries washer 13 for closing the waste-valve seat 9. d The mainjinletvalve lO is provided with a washer 14 for closingagainst the inlet-seat.

The upper end of the valve-rod 11 is screwed into a cylindrical coupling. 15, and the upper end of this coupling is swivelly connected to the lower end of a valve-stem "16 which works through a threaded stuflingbox 17 on the upper end of a hollow cast head 18. The hollow head 18 communicates at its lower end with the stand-pipe and at one side it is connected to the delivery-pipe 19 by a detachable coupling 20. "Thehead top of the coupling 21 and the upper face of 8 is provided a with a downwardly-facing 18 is screwed to the upper end of a sleevehead is screwed in place, abuts against the] the'bar 22. A swivel connection between the i It wi 1 be observedthat when the stem 16 is screwed: down, the inlet-valve is closed and the waste-valve willbe opened, to thereby drain the stand-pipe; and when the main valve is opened, the drain-valve will be vertical alinement with the waste-valve seat by meansof a guide-lug 27 and also by the guidebar 22. When it is desired to withdraw the valves upwardly through the ceed as follows: I first unscrew the coup ing 20 to thus permit the head 18 to be unscrewed from its coupling-sleeve, 21; this enables the stem 16 to be detached from the couplingmember 15. Then the guide-bar is is lifted out of the notches, whereu on the coupling member 15 may be rotated 1n a direction to carry the waste-valvef12 away from the lug 27. When the waste-valve 12 closed. The drain-valve is maintained in stand-pipe for the purpose of repair, I rohas thus been rotated to a point from under the downwardly-facing valve-seat 9, as shownin dotted linesin Fig. 1, the valverod and attached valves may be lifted entirely out of the stand-pipe, the outlet of the valve-chamber 6 and the internaldiameter ofthestand-pipe 5being sufliciently greater than the valve structure, to permit this upward withdrawal of the valve structure.

In this way, I avoid the necessity of digging upthe stand-pipe and the, valve-chamber 6 should the same be buried in the ground.

I have entitled my invention a hydrant,

but I do not intend restricting the scope of my invention by using this name, as it will be obvious to those persons having 'knowledge ofthe plumbing trade that the invention may be embodied in appliances which are known in the trade by other names; for instance, such devices as are known by the names street washers, stop-waste cocks or fire hydrants. It will be obvious also that the design may be altered in many ways to suit the needs; for instance, the outlet and inlet may be changed or reversed andthe form of the valve may be changed without de arting from the spirit of my invention.

at I claim as new is:

1. In a hydrant, a stand pipe having a.

valve-chamber attached to its lower end, this head which when in valve-chamber being provided with a bottom inlet l'iaving an upwardly-facin' val've-seat and also a waste-outlet provi ed with a downwardly-facing valve-seat, a valve-rod depending into said valve-chamber and carrying a valve-means comprising a down: wardly-tacing inlet-valve and an upwardlyfacing waste-valve", means on the upper end of the stand-pipe for reciprocating said valve-rod, these means embodying devices which permit the valve-rod to be rotated sufficiently to bodily swing the waste-valve laterally from under the waste-valve-seat, to thereby permit the valve-rod and valves to be moved upwardly through the standipe, the diameter of the outlet of the valve-c amher and the internal diameter of the standpipe being greater than the diameter of the valve-means, to permit said upward withdrawal of the valves; I

2. In a hydrant, a stand-pipe having a valve-chamber attached to its lower end, this valve-chamber being provided with a bottom inlet having an upwardly-facing valve-seat and also a Waste-outlet provided with a downwardly-facing ofiset valve-seat, a valverod depending into said valve-chamber and carrying a valve-means comprising a downwardly-facing inlet-valve and an ofiset upwardly facing waste-valve, means on the upperend of the stand-pipe for reciprocating said valve rod, these means embodying guidemeans for the valve-rod and a remoyable i ace locks the guideme ans in assembled re ation and which when removed from the stand-pipe permits the valve-rod to be rotated for the purpose set forth, said stand-pipe and the outlet of saidvalve-ch'amber having a greater diameter than said valve-means; I

3. In a hydrant, a stand-pipe having a valve-chamberattached to its lower end, this valve chamber' being provided with a bottom inlet having an upwardly-facing valve-seat and also a waste-outlet provided with a downwardly-facing ofl set valve-seat, a valverod depending into said valve-chamber and carrying a valve-means comprising a downwardly-facing inlet-valve'and an o flset upwardly-tacin waste-valve, means on the upper end of t e stand-pipe for reciprocating said valve-rod, these means embodying a hollow head detachably connected to the upper said valve-rod to altern end of the stand pipe, thisheitd being provided with a lateral discharge-nipple and means 'for detachably coupling it to the delivery-pipe, a screw valve-stem working down through the head, a guide-coupling swi'velly connected to said stem and extending down into the stand-pipe, this guidecoupli'ng being provided with a transverse slot, and a guide-bar having its ends held in placeby said head, said stand-pipe andthe outlet of said valve-chamber havinga greater diameter than said valve-means.

4. In an apparatusof the class set forth, a valve-chamber having an oflset inlet and a waste-outlet and also a main-outlet, a stand-pipe attached to the main-outlet of said valve-chamber, a valve-rod extending down through thestand-pi e and into the valve-chamber and provided with a valve for said inlet and also an ofisetyalve for said waste-outlet, the outlet of said valve-chamber and the diameter of the Stand-pipe being such as to permit the valve-rodcarrying' the valves to be lifted up throu the same, and means on top of the stand- "1P6 for operating yopen and close said inlet and said waste-outlet.

5. In an apparatus of class set' torth', a. yalve chamhe'r havingan inlet and a wasteoutlet and a main-outlet, said inlet and said waste-outlet facing in opposite directions, a stand-p'pe attached to-the outlet of said valve-c amber, a valve-rod extending down through the stand-pipe and into" the valvechamber and carr mg two valves, one for the waste-outlet and the other for the inlet, the diameter of said main-outlet and the stand pi connected thereto being such as to permit the valves to be raised up through the stand/wipe, means mounted on the top of the stand pi e for raising and Iowering' the valve-rod em odyin a removable head,these means embodying evices which permit the.

valve-rod to be rotated sufieientl. to bodily swing the waste-valve laterally rom un'der the waste-outlet, and uidi g means for the valve rod adapted to e reteased when said head is detached from the stand-pipe 'to thereby permit the valve-red to be rotated for the purpose set forth. 7

In testimony whereof I hereunto aflix my signature.
